OAKLAND, Calif. --

A second grade teacher in Oakland was placed on leave after kids in his class reportedly engaged in sexually activity.The district is investigating reports of two incidents. One involved several students taking their clothes off, and the other involved two students engaging in oral sex.

The teacher, whose name has not been released, told investigators he did not see any of the acts that authorities suspect occurred last week.

"He's saying he has no knowledge of the reports, and we have to see how we can reconcile these stories and reconcile them," said Troy Flint, a spokesperson for the Oakland Unified School District.

"You have a beautiful principal here who holds her school down. I can just say it was the ignorance of that teacher," said parent Lataya Young.

The teacher was barred from campus at least until the investigation is completed.

Meantime, the students believed to be involved in the sexual acts were not accused of any wrongdoing.
